The mass of unit volume of a material at a specified temperature.

A positively charged ion that migrates through the electrolyte toward the cathode under the influence of a potential gradient. See also anion and ion.

Fracture of a metal during quenching from elevated temperature. Most frequently observed in hardened carbon steel, alloy steel, or tool steel parts of high hardness and low toughness. Cracks often emanate from fillets, holes, corners, or other stress rais ...

A decrease in the polarization of an electrode; the elimination or reduction of polarization by physical or chemical means; depolarization results in increased corrosion.

A thin, tightly adhering oxide skin (only a few molecules thick) that forms when steel is tempered at a low temperature, or for a short time, in air or a mildly oxidizing atmosphere. The color, which ranges from straw to blue depending on the thickness of ...

An anode that is insoluble in the electrolyte under the conditions prevailing in the electrolysis.

The destruction of adhesion between a coating and the surface coated.

The number of cycles of stress that can be sustained prior to failure under a stated test condition.

Splitting (fracture) of a crystal on a crystallographic plane of' low index.

Foreign substance which comes from the environment, adhering to a surface of a material

In austenitic stainless steels the precipitation of chromium carbides, usually at grain boundaries, on exposure to temperatures of about 550 to 850

(Galvanic Corrosion) Corrosion resulting from dissimilar metal contact.

The range of the stress-intensity factor during a fatigue cycle.

A compound with a central atom or ion bound to a group of ions or molecules surrounding it. Also called coordination complex. See also chelate, complexation, and ligand.

Ability of a metal to withstand corrosion in a given corrosion system.

A pair of dissimilar conductors, commonly metals, in electrical contact. See also galvanic corrosion.

The rate of crack extension caused by constant-amplitude fatigue loading, expressed in terms of crack extension per cycle of load application.

The ratio of the electrochemical equivalent current density for a specific reaction to the total applied current density.

A cell developed in an electrolyte resulting from electrical contact between two dissimilar metals. See galvanic corrosion.

A substance that produces depolarization.
